Description
Technical field
The invention belongs to electric automobile field, more particularly, to a kind of method that BMS distributes collection plate address automatically.
Background technology
Cell management system of electric automobile (BMS) is the important tie for connecting vehicle mounted dynamic battery and electric automobile, is electricity
Critical component in electrical automobile.BMS mainly includes master control borad and multiple collection plates, and collection plate mainly gathers each monomer in battery
The message such as the temperature of voltage and inside battery of battery, and these information are sent to into master control borad by CAN lines, it is each in order to recognize
The information that individual collection plate sends, the CAN message that each collection plate sends have different ID values, therefore each collection plate in hardware
Or software has differences.
Communication inside electric automobile between each functional part is realized by CAN network, and is closed in electric automobile
Key member battery management system（BMS）Internal communication is also to be realized by CAN.CAN has communication speed height, reliability
The features such as good, strong antijamming capability, high cost performance.
In prior art, the CAN addresses of collection plate solidify in a program, and the collection plate of different address has differences, it is impossible to
General, this brings many inconvenience to work such as production and after-sales services.
The content of the invention
In view of this, it is contemplated that proposing a kind of method that BMS distributes collection plate address automatically, deposited with solving collection plate
In difference, it is impossible to general problem.
To reach above-mentioned purpose, the technical scheme is that what is be achieved in that：
A kind of BMS distributes the method for collection plate address automatically, including：
1）A divider resistance is concatenated in each collection plate；
2）Divider resistance in different acquisition plate is mutually concatenated；
3）The voltage of power supply is constant DC voltage, and power supply powers for series resistor；
4）Voltage collection circuit in each collection plate gathers the magnitude of voltage of corresponding divider resistance, according in collection plate
Translation-protocol export an ID value, the ID values be the collection plate address.
Further, the resistance of each divider resistance is identical.
Further, the divider resistance is on the circuit board of collection plate.
Further, the divider resistance is also outside the circuit board of collection plate.
Relative to prior art, the method that a kind of BMS of the present invention distributes collection plate address automatically has following excellent
Gesture：The crash consistency of each collection plate is this invention ensures that, while and master control borad can be made to go out respectively according to different CAN Address Recognitions
The information that individual collection plate sends, works to production and after sale there is provided great convenience.

The connection of two element internals.For the ordinary skill in the art, above-mentioned term can be understood by concrete condition
Concrete meaning in the present invention.
Below with reference to the accompanying drawings and in conjunction with the embodiments describing the present invention in detail.
As shown in figure 1, a kind of method that BMS distributes collection plate address automatically, including：
1）A divider resistance is concatenated in each collection plate；
2）Divider resistance in different acquisition plate is mutually concatenated；
3）The voltage of power supply is constant DC voltage, and power supply powers for series resistor；
4）Voltage collection circuit in each collection plate gathers the magnitude of voltage of corresponding divider resistance, according in collection plate
Translation-protocol export an ID value, the ID values be the collection plate address.
Wherein, the resistance of each divider resistance is identical, and resistance quantity is N number of, and N is the quantity of collection plate.
Wherein, the divider resistance is on the circuit board of collection plate.
Wherein, the divider resistance is also outside the circuit board of collection plate.
The concrete grammar of distribution ID addresses：BMS includes master control borad and multiple collection plates.One is concatenated in each collection plate
Individual divider resistance, the divider resistance in multiple collection plates is concatenated, and each divider resistance connects corresponding collection plate voltage acquisition
Circuit.The power supply for determining voltage is adopted to power for series resistor circuit, as divider resistance quantity is, it is known that divider resistance
Resistance is identical, and the magnitude of voltage that different voltage collection circuits collect correspondence divider resistance is different, and each collection plate is according to collecting
Magnitude of voltage, according to the translation-protocol in the collection plate, generation belongs to the ID values of the collection plate.
Each collection plate realizes communication with master control borad by CAN network, if multiple collection plates send identical information to master control
Plate, as each collection plate has different ID values, master control borad can identify different collection plates by difference ID values, therefore main
Control plate can preferably monitor battery system.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
